When you post a WL book it automatically gets offered to the 1st person in the WL line. So if it's just on your shelf then it's not a WL book.

I see you just joined today. Under you Main account page will be tabs for any pending transactions. If someone is requesting one of your books it'll be right there for you to accept and choose a mail by date. If a book is on WL hold for someone then there will be a tab that says Wish Lists Holds which will list any books that are being offered to a wisher.

If the book is WL and autorequest then it goes into 1hr Buyers Remorse Hold first. During that hour it shows on your Bookshelf with a ! that says "on 1 hr buyers remorse hold" before it shows up as a book request. Only you can see the book on your shelf at this time.

Can I ask why you posted them without an ISBN? Did they not have an ISBN on them or did the ISBN bring up the wrong binding?

I ask because the book by John Piper you have listed as a paperback is WL in paperback under an actual ISBN. Yours has a PBS generated ISBN. You could try tagging the WL version with the ISBN of yours. Do "1 posted under ISBN xxxx".

If your book has a ISBN printed on it, remove it from your bookshelf and repost it with the ISBN. Don't try to enter the dashes when you type the ISBN numbers in to post the book. People are much more likely to be able to find it if it is posted to its correct ISBN.

If you aren't sure what the ISBN is ... try Googling it, I'm sure there will be pictures of it. It's a 10 or 13 digit number that is usually printed near the bar code on the book, although it can be in other locations. A 13 digit ISBN starts with "978" in the US. 10 digit ISBNs usually start with "0". Lots of times, they are actually labeled 'ISBN" right on the book.

If your book doesn't have an ISBN printed on it, then what Mary suggested is a good idea, tag it.

You should also have a Tour Guide available to you, who can help you with this.
